Coordinate transformations in FLUENT -- CFD Online Discussion Forums

quantum.tejas New Member Tejas C Join Date: Apr 2010 Posts: 10 Rep Power: 16	I am having trouble understanding how Fluent measures angles in the Cartesian coordinate system. I need it to define 3 angles for a flapping wing system. FLUENT takes it as rotational velocities. When i use 2 angles, the behavior is fine but when a third angle is introduced, it goes haywire. I doubt it whether the Eulerian transformations work the same way in FLUENT as in a general math case. Could anybody shed some light?
